A precise pressure regulating valve belongs to the technical field of pressure regulating valves. Comprising a valve body, an inlet pipe is fixedly connected to the left side surface of the valve body, an outlet pipe is fixedly connected to the right side surface of the valve body, a top cover is fixedly connected to the upper surface of the valve body, a water passing cavity is formed in the valve body, a blocking piston is slidably connected into the water passing cavity, and a supporting spring is fixedly connected to the blocking piston; the upper surface of the blocking piston is fixedly connected with a movable rod, and pressure adjusting mechanisms are arranged in the inlet pipe and the outlet pipe. According to the precise pressure regulating valve, the pressure regulating mechanism is arranged, opening or closing of the blocking piston is automatically controlled according to the pressure difference between the water pressure in the inlet pipe and the water pressure in the outlet pipe, the pressure i
